WILLIAM HOWARD BENDER, OF BROOKLYN, NEW YORK.

ADVERTISING NOVELTY.

SPECIFICATION forming part of Letters Patent No. 756,206, dated April 5,1904.

Application filed August 11, 1903.

To (ZZZ whom it may concern:

dent of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Advertising Nov--elties, of which the following is aspecification.

The invention relates to improvements in advertising novelties; and itconsists in the novel features and combinations of parts hereinafterdescribed, and particularly pointed out in the claims.

The object of the invention is to producea machine or apparatus for theattractive display of advertising or other matter and comprising in itspreferred embodiment a general supporting-frame, a group of individualrollers carrying flexible curtains wound thereon at the upper end ofsaid frame, a like group of individual rollers with curtains woundthereon at the lower end of said frame, movable carriers supporting saidrollers at the opposite ends of said frame, a traveler adapted to bemoved as rapidly or slowly or continuously or intermittently as may bedesired intermediate said groups of rolled curtains, clutches carr-iedby said traveler for engaging when the tr'aveleris at the lower end ofits path one of the curtains of the lower group and unrolling the sameupwardly (for displaying the matter thereon) as the traveler moves tothe upper end of its path, additional clutches carried by said travelerfor engaging when the traveler reaches its upper position one of thecurtains,

of the upper group and unrolling the same downwardly (for displayingthematter thereon) as the traveler returns to its lower position toallow the curtain previously unrolled upwardly to become rewound anddelivered to the lower roller-carrier, and means connected with saidtraveler for actuating the re* spective roller-carriers when saidtraveler approaches the same and delivers a rewoundalready-displayedcurtain thereto to move the next curtain to bedisplayedto the clutches of V the traveler, so that the same may be unrolled uponthe succeeding'movement of said trav- -eler. Every time the travelerreaches the lower end of its path it releases an alreadydisplayedcurtain of the lower group and en Serial No. 169,094- (No model.)

gages the next curtain of the said group to be displayed'by beingunrolled upwardly, and every time the traveler reaches its upper position it releases an already-displayed curtain of the upper group andengages the next curtain of the said group to be displayed by beingunrolled downwardly,'and thus the traveler while in motion in eitherdirection is constantly unrolling one curtain for the display of thematter thereon and allowing the last previously-displayed curtain torewind upon its roller.

In accordance with my invention I am enabled to employ a number ofcurtains at therespective ends of the apparatus and to display thesecurtains in succession, there being no period during the employment ofthe apparatus when its entire front field is not covered by eitherportions of an unrolling curtain and a receding curtain or by acompletely-unrolled curtain. My purpose is to allow the traveler toremain at rest a due length of time when it reaches the ends of itspath, so that the mat ter on an individual curtain may remain displayeda proper period and occupy the entire front field of the apparatus.

An essential and predominating feature of my invention is that thetraveler carries the rolled curtains and effects the unrolling of thesame by its movement as distinguished from engaging the outer end of thecurtain and pulling it either upwardly or downwardly, and this is a veryimportant feature in its effect upon the observer and in respect of theefficiency and desirability of the apparatus, because with my inventionthere is no movement of the unrolled portion of the curtain, (such aswould be the case, for illustration, in pulling down the commonly-usedwindowcurtain,) and the matter to be displayed gradually grows into viewand remains stationary during the movement of the carrier to unroll thecurtain, an efficient display being thereby made and an attractiveeffect produced. During the rolling up of the curtain the observer doesnot see any movement in the curtain itself; but the displayed mattergradually disappears, and the gradual appearing and disappearing of thedisplayed matter without apparent movement of the curtain is animportant feature in the operation of the apparatus constituting myinvention.

The invention and satisfactory means for carrying the same into effectwill be fully understood from the detailed description hereinafterpresented, reference being had to the accompanying drawings, in whichFigure 1 is a front elevation of a display apparatus constructed inaccordance with and embodying the invention, the traveler which movesbetween the upper and lower groups of curtains being shown in its lowerposition with one of the upper curtains drawn downwardly to occupy thefront field of the apparatus. Fig. 2 is a rear elevation, partly brokenaway and partly in section,of same, a portion of the rear part of thetraveler being broken away to more fully disclose the lower group ofrollers. Fig. 3 is a vertical section of same on the dotted line 3 3 ofFig. 1. Fig. 4is an elevation looking at the right-hand side of Fig. 1of the end disk constituting a part of the carrier for the upper groupof rollers. Fig. 5 is a like view of the end disk constituting a part ofthe carrier for the lower group of rollers. Fig. 6 is a horizontalsection through the apparatus on the dotted line 6 6 of Fig. 2. Fig. 7is a detached view taken from the rear of the machine of a portion ofthe traveler and the sprocket-chain by which said traveler is given itsvertical reciprocating movement intermediate the two groups of curtains.Fig. 8 is a detached elevation of one of the end plates connected withthe front part of the traveler and utilized for carrying buffers, ashereinafter explained. Fig. 9 is an enlarged view corresponding with theupper portion of Fig. 3, but showing the traveler as having nearlyreached its upper position to deliver the curtain exposed in Fig. 1 tothe upper carrier preparatory to the rotation of said carrier forpositioning another curtain-roller to be taken by the traveler and drawndownwardly when said traveler again moves to its lower position. Fig. 10is a detached edge view of a dog shown in Fig. 9 for normally lockingtheupper carrier in stationary position. Fig. 11 is a detached edge view ofa weighted pawl carried by the traveler and utilized for tripping thedog shown in Fig. 10 and rotating the upper carrier to a limited extenteach time the traveler arrives at its upper position. Fig. 12 is anenlarged detached side View; partly in section and partly broken away,of one of the curtain-rollers with a portion of one of the curtainsready to be applied thereto, the curtain having tongues to enter theslots in the barrel of the roller. Fig. 13 is adetached elevation of theleft-hand end of the curtainroller shown in Fig. 12, and Fig. 14 is avertical section through the apparatus on the dotted line 14 of Fig. 1.

The general supporting-frame of the apparatus comprises a top plate 20,a base-plate 21, two right-hand standards 22 22, two correspondingleft-hand standards 23 23, a rear central guide-rod 24, cross-bars 25,connecting at their upper portions the standards 22 22 and the standards23 23, and cross-bars 26 26, connecting at their lower ends thestandards 22 22 and the standards 23 23, the said standards 22 23 andguide-rod 24 being secured at their upper and lower ends to the topplate and base-plate 21, respectively.

Immediately below the top plate 20 is mounted a rotary carrier for theupper group of spring curtain-rollers, said carrier comprising a shaft27, loosely mounted in apertures in the cross-bars 25, disk-plates 2829, secured on said shaft 27 and rods 30, which connect the disks 28 29and with said disks form a skeleton cylindrical frame, which is adaptedto carry the upper group of curtain-rollers with the curtains woundthereon. The rods 30 enter apertures 31 in the disks 28 29, whichapertures are equidistant from each other, as illustrated in Fig. 4. Thedisks 28 29 of the upper carrier are formed with slots 32, which areopen at their outer ends and are intermediate the apertures 31, andwithin the slots 32 are placed the ends of the shafts 33 of the springcurtain-rollers 34, as clearly illustrated in the drawings. One end ofthe roller-shaft 33 is round, as shown in Fig. 12, and this round end ofsaid shaft fits within the slots 32 of the disk 29, while the other endof the shaft 33 for the upper group of curtains is flattened at itsopposite sides and snugly fits within the slots of the disk 28 for theupper carrier, the flattened sides of said end of the shaft 33 engagingthe side walls of the said slots in the disk 28 and preventing theunwinding of the curtain while its roller is held by the disks 28 29.The upper rollers are numbered 34 and the lower rollers 35, and theupper curtains are numbered 36, while the lower curtains are designatedby the numeral 37. The rollers 34 35 correspond exactly with each other,but are reversely arranged thatis to say, that the flattened end of theshaft 33 for the upper rollers is at the lefthand side of the apparatus,as shown at the upper portion of Fig. 1, while the like ends of theshafts of the lower rollers are at the right-hand side of the apparatus,as may be observed by looking at the lower right-hand portion of Fig. 1.The spring-rollers may be of any suitable construction and in thepresent instance comprise a barrel 38, mounted upon the shaft 33 andinclosing a coiled spring 39, Fig. 12, one end of which is fastened tosaid shaft, while the other end of said spring is fastened to a hub 40,fitted in the end'of the barrel 38 and adapted to be held in rigidrelation to said barrel bymeans of a screw 41. Upon the flattened outerend of the shaft 33 is secured a disk 42, which matches against theouter end of the hub 40, and the said shaft 33 passes freely through anaperture in said ihub 40 and may rotate within said hub. The

hole in the disk 42, through which the end or tion of this shaft towardthe right winding up the spring 39. When the curtain-rollers are in themachine or apparatus made the subject of this application, the springs39 are always under tension, the springs being placed under tensionbefore the rollers are introduced into the upper and lower carriersprovided for them. In order that the rollers may be conveniently handledpreparatory to their introduction into the machine and while the springs39 are under tension, I provide a slidable pin 43, Fig. 13, set within agroove formed in the hub 40 and having a head 44, exposed in a slot 45,formed in the barrel 38, this pin 43 under manual manipulation beingadapted to he slid outwardly, so that its outer horizontal end may enteran aperture 46in the disk 42 for the purpose of locking the disk 42,shaft 33, and hub 40 together, whereby the said shaft 33 is preventedfrom turning under the action of thespring 39' and the entire roller maybe conveniently handled. After the roller is introduced to the'slots 32of the disks 28 29 the pin 43 will be moved inwardly by pressure appliedto its head 44, whereby the said pin will be withdrawn from the disk 42,and the spring 39 will be thereby released and left free to exert itstension against the curtain 36. The curtains 36 are preferably of muslinor other textile fabric and are detachably secured to the rollers 34,and in the present instance the curtains 36 are, as shown in Fig. 12,provided with tongues 47, to be inserted through slots 48 in the barrel38 of the roller 34. These tongues 47 being of suitably stiff materialwill, when bent angularly after en-' tering the slots 48, serve toconnect the inner edge of the curtain with the barrel 38, and when thecurtain 36 is given one or more turns round the barrel 38 the tongues 47will be thereby bound in position, and the entire curtain will becomedetachably connected with the entire roller.

I do not limit myself to any special means for or manner of connectingthe inner end of the curtain 36 with the barrel 38 of thecurtain-roller, because it is evident that said end of the curtain maybe secured to the barrel 38 in many ways.

The curtain 36 after its inner end is secured to the barrel 38 is woundupon the latter in the ordinary manner of a window-curtain, and theouter edge of the curtain 36 is providedat its center and ends withhooks 49 to hook upon the rods 30, connecting the disks of theroller-carrier, the said hooks 49 being i simply cemented or otherwiseapplied to the outer edge of the curtain 36 and being adapted to passupon the said rods 30, as illustrated in Fig. 9.

' The curtain-rollers 34, comprising the upper group, correspond exactlywith one another, and each has a curtain 36 woundupon it, 'and each ofsaid rollers has its shaft 33 set within] alined slots 32 of thedisks'28 29, while the outer end ofthe curtain is held upon a rod '30adjacent to said slots, as isillustrated in Figs. 3'and 9. Upon theapplication of the rollers, with the curtains wound thereupon, to thedisks 28 29 the pin 43 will be withdrawn from the disk 42,- so that thespring 39 may exert its force against the curtain, the tendency of thespring being to draw the curtain toward its roller and pull the outerend of the curtain against its rod 30. The tension of the spring 39 willbe such that it will by its pull on the curtain hold the' roller-shaft33 within the slots 32 of the disks 28 29 until by the means hereinafterdescribed the said shaft 33 is positively withdrawn from said slots 32by a force superior to the tension of the spring 39. The rollers areshown in po-' sition in the slots 32 in Fig. 9, and they are there heldby the tension of the springs 39 against the curtains 36. The base orsaid slots 32 is set inwardly beyond the line of the rods 30. V Thecarrierfor the upper group of rollers comprises the shaft 27, disks 2829, and rods 30, said disks having the slots 32, and in the presentinstancethe disks 28 29 are each provided with six of the slots 32, andthe said disks'are'connected by six of the rods 30, and when the uppercarrier is thus formed it will accommodate six of the rollers 34 withtheir curtains 36. The disk 29 of the upper carrier is provided with aseries of pins 50, to be engaged by a locking-dog 51,- Figs. 3, 9, and10, for holding the carrier at the end of each of its intermittentmovements, the dog 5l being shown in its locking position in Fig. 3 andin its released position in Fig. 9. The dog 51 is firmly drawn againstthe pins 50 by means of a coiled spring 52, and the means for moving thedog 51 outwardly from the pins 50 is a pawl 53, carried by the traveler54, said pawl 53 being a pivoted weighted pawl held in its uprightposition by a pin 300, Fig. 9, and having at its upper 'end ahorizontally-extending pin 55 in position when the traveler 54 isreaching its upper position to move against the inclined flange 56 atthe lower end of said dog 51 and push said dog at its lower endrearwardly from the pins 50. The rearward'moveinent or tripping of thedog 51' is to enable thepawl 53 on its further upward movement to impartan intermittent rotary motion to the and that upon the further upwardmovement of the traveler 54 and pawl 53 the latter, pressing againstsaid pin 57, will turn the upper roller-carrier one-sixth in the presentcase of a rotation or until the pin 50, which in Fig. 9 is directlybelow the upper pointed end of the pawl 53, has reached a position inline with the notch 58 6f the dog 51. At each upward movement of thetraveler 54 the pawl 53 will disengage the dog 51 and rotate the uppercarrier a definite distance sufficient to cause said carrier to positionanother roller to be taken and drawn downwardly by the carrier on thenext descent of the latter, as will be hereinafter more fully explained.The series of pins 57 are in the form of a lantern-wheel, as may be seenon reference to Fig. 1, and they are provided to cooperate with the pawl53 in enabling the latter to eflect an intermittent rotation of theupper roller-carrier. The pins 50 are simply stop-pins to cooperate withthe pivoted spring-dog 51 for holding the said carrier at the end ofeach of its intermittent movements.

The carrier for thelower group of curtainrollers corresponds with thecarrier for the upper group of said rollers, and the said lower carriercomprises a shaft 59, mounted in crossbars 26 of the machine-frame,disks 61, secured on said shaft, and rods 62, connecting said disks, therods 62 corresponding exactly with the rods 30 of the upper carrier, thedisk 60 corresponding exactly with the disk 28 of the upper carrier, andthe disk 61 corresponding exactly with the disk 29 of the upper carrierand having on its outer face, correspondingly with the disk 29 of theupper carrier, the series of stop-pins 63, and the series of pins 64constituting a lantern-wheel for cotiperation with adog and pawl 66,corresponding with the dog 51 and pawl 53 for the upper carrier, withthe exception that the said parts are reversed in position, the dog 51for the upper carrier extending downwardly from its pivot and the dog 65extending upwardly from its pivot. The dog 65 and stop-pins 63 for thelower carrier operate exactly as the stop-pins 50 and dog 51 for theupper carrier, and the pins 64 of the lower carrier cooperate with apawl 66, carried at the left-hand end of the traveler 54, and areidentical in construction and operation with the pawl 53 for the uppercarrier, with the exception that the active end of the pawl 66 hangsdownwardly, while the corresponding end of the pawl 53' for the uppercarrier extends upwardly. The pawl 66 is held in its upright position bya pin 301. (Shown in Fig. 14.) It seems to be unnecessary to describe indetail the action of the pins 63, pins 64, dog 65, and pawl 66 for thelower carrier, because such operation is identical with the operation ofthe like parts above described with respect to the upper carrier; nor doI deem it necessary to enter into a detailed description of the disks 6O61 and rods 62 of the lower carrier, because these parts are identicalwith the like elements'of the upper carrier, with the exception that theslots of the disks 6O 61 are reversely arranged to the slots 32 of thedisks 28 29, as is indicated by comparison of Figs. 3 and 14, thisdisposition of the slots 32 being necessary because the upper carrierturns toward the front and downwardly to deliver its curtains one afteranother in succession to the traveler 54, While the lower carrier turnsupwardly and toward the front to deliver its curtains one after anotherin succession to the said traveler.

The rollers 35 for the lower carrier correspond exactly with the rollerillustrated in Fig. 12, and the curtains 37 for the lower group ofrollers correspond exactly with the curtains 36 of the upper group, theinner ends of said curtains 37 being secured to the rollers and theouter ends of said curtains being fastened to the rods 62.

The traveler 54 is moved downwardly and upwardly between the twocarriers for the upper and lower groups of spring curtain-rollers, andthe said traveler comprises a front horizontal bar 67, a rear horizontalbar 68, Fig. 6, and end bars 69 70, these end bars 69 70 havingright-angular bent ends engaging the standards 22 23, as shown in Fig.6, the said bars 69 70 being thus made to span the said standards 22 23and the latter serving as guides for the traveler 54. The rear bar 68 isfastened by screws to the inner or rear ends of the bars 69 70, as shownin Figs. 2 and 6, and the front bar 67 is a plain fiat bar fastened byscrews at its ends to the plates 71, one of the latter being fastened toeach end of the bar 67 and one of these plates being shown in detail inFig. 8. The plates 71 are shown in front elevation in Fig. 1, and theyare held upon the front ends of the bars 69 7 O by means of screws 72and washers 73, said washers lying flat against the face of said plates71 over elongated slots 74, formed in said plates and through which thescrews 73 pass. The screws 73 are rigid with the front ends of the bars69 7 O, and through the heads of these screws freely pass vertical pins174, whose ends are secured in forwardly-projecting ears 75, formed onthe plates 71. Upon the pins 174, intermediate the heads of the screws73 and cars 75, are arranged coiled springs 76. The front bar 67 is bymeans of the plates 71, screws 73, pins 17 4, and springs 76 secured tothe bars 69 7 O and at the same time allowed vertical yielding movementon the ends of said bars 69 70. The springs 76 operate as buffers orcushions at the ends of the line of movement of the traveler 54. At thelower end of the front of the machine or apparatus is provided thevertical stop-pins 77, and at the upper end thereof stop-pins 78 areprovided. these stop-pins 77 78 being in line with each other and withthe cars on the plates 71. When the traveler 54 descends, the lower cars75 will strike upon the pins 77 and the bar 67 will become arrested,while illustrate the traveler in its lower position,

with the lower ears of the plate 71 arrested upon the upper ends of thepins 77. When the traveler 54 reaches its upper position, the pins 78will arrest the bar 67, while the traveler 54 moves to a slight extentfarther upward, the screws 72 at such time moving upwardly in the slots74 and the upper springs 76 cushioning the bar 67. The bar 67 isarranged to pass very closely to the upper and lower carrier-disks whenat the ends of its line of movement, as may be understood on referenceto Fig. 3, and hence it is desirable to arrest said bar slightly beforethe traveler 54 completes its movement, so that said bar may notinterfere with the proper operation of said carrier-disks, and it is forthis reason that I provide the stop-pins 77 78, plates 71, pins 17 4,and springs 76 for arresting and cushioning the bar 67. j The rear bar68 of the traveler 54 is provided with brackets 79, carrying verticalpins 80, upon which is arranged a frame 81 and coiled springs 82, thesesprings being arranged one above and one below each end of the frame 81for cushioning said frame, the latter being allowed a limited yieldingmovement upon the pins 80. The frame 81 comprises a front bar 83 andarear bar 84, the-latter having vertical openings 85,and.transverseslots 86 87 ,as more fully illustrated in Figs. 6 and 7, and the frame81 is directly back of the sleeve 88, mounted uponthe vertical standard24, the latter serving as a guide for said sleeve 88- during thevertical movement of the traveler 54. The sleeve 88 is fastened to andmoves with the bar 68 of the traveler 54, and at its upper and lowerends the said sleeve 88 is equipped with grooved rollers 89,which guideupon the aforesaid standard 24. The traveler 54 receives its movementfrom a driving-shaft 90, sprocketwheel 91, secured on said shaft,thesprocketchain 92,engaging said wheel 91,and a sprocket-wheel 93,alsoengaged by said chain 92,the said chain 92 carrying a pin94,preferablyhaving thereon a roller 95 in engagement with the frame 81. When theshaft. 90 is in motion, it will, through its sprocket-wheel 91, impartthe usual movement to the sprocketchain 92, and said chain will, throughits pin 94, impart motion to the traveler 54 by reason of the engagementof said pin with the frame 81. When the traveler '54 is moving upwardly,the pin 94 and roller 95 will be in the slot 86 of the frame 81 and,pressing against the upper wall of .said slot, will cause said frame 81and traveler 54 to move upwardly. When the traveler reaches its upperposition, the slot of the frame 81 will pass upon opposite sides of-theshaft 94 of ther I sprocket-wheel 93, and thus allow the slots 86 87 ofthe frame 81 to reach the upper edge of I said wheel, this beingfor thepurpose of enabling the pin 94 and roller 95 to pass from the slot 86 ofsaid frame 81 and enter theslot 87 of said frame, so that as the saidpin and roller is moving downwardly on the descending side of thesprocket-chain 92 they may by pressing against the lower wall of theslot87 cause the traveler 54 to descend with it.

VVhen the traveler reaches the lower end of its movement, the slot 85 ofthe frame 81 will pass over the driving-shaft in the rear ofthesprocket-wheel 91, and thus as the chain 92 continues its movement thepin 94 and roller may pass from the slot 87 back into the slot 86 of theframe 81 and then, when ascending efiect the upward movement of thetraveler 54. The traveler 54 is thus moved both upwardly and downwardlyby means. ,of'the pin 94 and roller 95, carried by the chain 92, saidroller and pin being in the slot 86 of the frame 81 during the upwardmovement of the traveler and in the slot 87 of said frame during thedownward movement of the traveler. When the frame 81 is at its upwardposition, it receives between its front bar 83 and rear bar 84 the uppersprocket-wheel 93, and when the frame 81 is in its lower position itreceives between its said bar 84 and bar 83 2. The shaft 94 for theupper sprocket-wheel :93 is held in the lower end of a hanger 95.

The frame 81 is cushioned by the springs 82,

so as to be slightly yielding, thus preventing the pin 94 and roller 95from binding against. the walls of the slots 86 87 when leaving onePower may,

slot and entering the other slot. be applied to the driving-shaft 90 inany approved way and by any approved means, the power mechanism fordriving the shaft 90 constituting no part of the present invention.

.In the present instance I illustrate the shaft 90 as being equippedwith a crank 961, by means of which said shaft will be rotated to effectthe movement of the sprocket-chain 92 and traveler 54.

The traveler 54 carries the weighted pawls 53 and 66, hereinbeforedescribed, the pawl 53 being pivotally secured to the bar 70 'of thetraveler 54 and the pawl 66 being .pivotally secured to the bar 69 ofsaid traveler.

-The traveler 54 also carries at its opposite ends pivoted clutch-bars96, these bars 96 being mounted upon pins 97, extending toward eachother from the bars 69 7 O of the traveler 54. The pins 97 have woundupon them coiled springs 98, whose ends, as shown in Fig. 3, bearagainst the bars 96 at the opposite sides of the pivot-points of thelatter, said springs exerting their force to keep the bars 96perpendicular, but yielding when one end or the other of said bars ispressed outwardly. The bars 96 are provided at their the lowersprocket-wheel 91, as shownin Fig.

upper ends with inclined surfaces99, leading downwardly to clutch-hooks100, and the said bars at their lower ends are provided with inclinedsurfaces 101, leading upwardly to clutchhooks 102, the purpose of theclutch-bars 96 being to engage the shafts 33 of the curtainrollerspresented to them when the traveler is reaching the ends of its line ofmovement. The shape of the interior walls of the clutchhooks 100 and 102conforms to the shape of the ends of the shafts 33 of thecurtainrollers.

The upper end of the left-hand bar 96 and the lower end of theright-hand bar 96 are bent frontwardly, so that the extremities of saidends may not when the traveler is reaching the ends of its line oftravel strike against the rectangular ends of the curtain-rollers thenin their path.

When the traveler 54 is reaching its upper position, the pawl 53 will,as hereinbefore described, trip the dog 51 in the manner shown in Fig.9, and the pointed end of said pawl will upon completing its upwardmovement effect a partial rotation of the upper carrier for thecurtain-rollers, this having the effect of moving the shaft of theroller immediately above the clutch-bars 96 downwardly against theinclined surfaces 99 of said bars and tilting said bars outwardly attheir upper ends, so that said shaft may pass below the hooks 100 ofsaid bars, whereupon, the ends of the said shaft having left the bars96, the upper ends'of the latter will under the influence 0f the springs98 return to their initial position and said hooks 100 will be directlyover the ends of said shaft, and thereupon the traveler 54 will movedownwardly, with two results, one being to carry the pawl 53 from thedog 51 and allow said dog to engage one of the pins and lock the uppercurtain-roller carrier in firm position and the second being that as thetraveler 54 moves downwardly the hooks 100 of the clutch-bars 96 willpass upon and engage the shaft of the curtain-roller which passed belowthem and draw said shaft and roller from their slots 32, as shown inFig. 3, the continued downward movement of the traveler 54 causing thecurtain to unwind from its roller and extend across the front field ofthe apparatus, so that the matter thereon may be fully displayed. Whenthe traveler 54 moves downwardly from its upper position, the pin 55 ofthe pawl 53 will descend upon and ride down the upper surface of theflange 56 of the dog 51 and finally pass off from said flange, said pawlat its upper end tilting rearwardly, due to the inclination of theflange 56, to permit said pin to pass said flange. When the traveler 54reaches the lower end of its line of movement, the pawl 66 will trip thelower dog to free the lower curtain-roller carrier and then turn saidcarrier to a limited extent for the purpose of causing the ends of theshaft of the curtainroller next below the clutch-bars 96 to moveupwardly along the inclined surfaces 101 and tilt the lower ends of saidbars outwardly, so that said shaft may pass above the hooks 102 of saidbars, so that upon the succeeding ascent of the traveler 54 the saidhooks 102 may pass upon and carry the said shaft, with its roller, fromthe slots of the lower carrier-disks and unroll the curtain from saidroller upwardly, as represented in Fig. 9, for the purpose of displayingthe advertising or other matter upon said curtain. The traveler 54 uponits descent thus carries downwardly one of the rollers from the uppercarrier, and upon its succeeding ascent carries upwardly one of therollers from the lower carrier, and upon the ascent of the traveler 54the display-curtain of the upper group gradually becomes rolled up uponits roller under the action of the interior spring 39. When the travelerreaches its upper position, it moves the ends of the shaft of the rollerinto the slots waiting to receive them of the upper carrier-disks 28 29,as shown in Fig. 9, and then upon the rotation of the uppercarrier-disks by means of the pawl 53 the shaft of this roller, whichhas just been returned to said disks, moves downwardly from the upperhooks 100 during the period that the shaft of the roller next above theclutch-bars 96 is turning downwardly to pass into position to be takenby said hooks 100 upon the next descent of the traveler 54. WVhen thetraveler 54 reaches its lower position, the hooks 102 will deliver theshaft of the roller previously carried upwardly by them into the slotsof-the lower carrier-disks 60 61 to the position shown in Fig. 3, andthen upon the lower pawl 66 imparting movement to the said disks thesaid shaft will be carried upwardly from the said hooks 102 and theshaft of the roller next below the clutch-bars 96 will be moved upwardlyinto position to be taken by said hooks 102 upon the next ascent of thetraveler 54. Thus the traveler 54 moves intermediate of the two groupsof ourtain-rollers, and upon each descent of said traveler theclutch-bars 96 will draw downwardly one of the rollers of the uppergroup and cause the curtain thereon to become unwound, and at the sametime the said clutchbars will deliver to the lower carrier the roller ofthat group which had been previously displayed, and upon each ascent ofsaid traveler 54 it will carry upwardly a roller of one of the lowergroups of curtains and unwind the curtain therefrom, while at the sametime the displayed curtain of the upper group will be returned to itscarrier. The traveler 54 therefore always when in movement carries acurtain of the upper group and a curtain of the lower group, unwindingand displaying one of the said curtains and allowing the rewinding ofthe other curtain preparatory to its delivery to its carrier. When thetraveler 54 is descending, the curtain of the upper group IIO is beingunwound for display and a curtain of the lower group is being wound upfor delivery to its carrier, and when the said traveler is ascending acurtain of the lower group is being unwound for display, while a curtainof the upper group is being wound upon its roller for delivery to itscarrier.

In the present instance I illustrate each of the carriers as beingequipped with siX of the spring-rollers with curtains thereon; but it isobvious that the said carriers may, according to their size, be equippedwith any number of curtains desired. The purpose of the invention is toprovide the upper and lower carriers with groups of curtains, so thatsaid curtains may one after another in succession be delivered to theclutch-bars 96 and unrolled by them, the carriers automaticallysupplying the clutch-bars 96 with the curtains in succession and saidclutch-bars restoring to the carriers the displayed curtains insuccession.

The shaft may be arrested when the traveler 54 is at the respective endsof its line of movement, so as to display the curtain then across thefront field of the apparatus as long 'as may be desired; but ordinarilythe shaft 90 will be arrested at each end of the line of travel ofthe'traveler 54: only for the fraction of a minute, and thus there willbe substantially a continuous display of the curtains, the latter insuccession being drawn across the front field of the apparatus.

The front bar of the traveler 54 substantially conceals from view thetwo curtain-rollers carried by said traveler.

In the foregoing description I have mentioned that the outer ends ofthe. display-curtains are provided with hooks to engage the rods of theroller-carriers; but I desire it to be understood that the invention isnot limited to any special method of or means for securing the outerendvof the curtains to said carriers.

The details of the apparatus hereinbefore' described may be modified inmany respects Without departing from the scope of my invention asclaimed; and I do not, therefore, limit my invention to such detailsfurther than as may be indicated in the following claims.
